Abstract:
A 43-year-old man with chronic renal failure who had been treated by continuous ambulatory peritoneal dialysis (CAPD) was admitted to our hospital because of dry cough. Blood gas analysis showed hypoxemia and metabolic alkalosis. Laboratory data showed elevated levels of phosphorus, BNP, and KL-6. Lung function tests showed restrictive ventilatory failure and impairment of diffusing capacity. Chest CT revealed centrilobular ground-glass opacification in both lung fields, irregular reticular abnormality in left lung field, and calcification around the left shoulder joint. Bronchoscopy revealed a white protruding lesion in the trachea and bronchial membranous portion. Calcified metastasis in the bronchus and lung was confirmed by transbronchial and lung biopsy. Because of no improvement by administration of sevelamer, he started with hemodialysis once a week in addition to CAPD. Cough and bilateral ground-glass opacity were improved.

Chronic Obstructive Pulmonary Disease III: Chronic Bronchitis Features
The Bronchial Tree
The trachea, commonly known as the windpipe, is a tube that connects the larynx (voice box) to the bronchi. At a point called the carina, it bifurcates into two primary bronchi. The right primary bronchus is wider, shorter, and more vertical than the left primary...
